It's a nice piece of information for anyone who wants to enter the market but I would rather suggest Binance and Coinbase as these platforms are reputed and everyone is familiar with it, I would suggest to go for Binance as it provides more features and gives better opportunity for traders. Because there are exchanges in CMC which has lower fee but they lack in security and non responsive support team.
